Patterns (Click on a thumbnail to get the full-size image)

I would build this helmet in the following order:

1. Cut out the two halves of the helmet plus the nasal and a 5/16" wide rib stop (the band that goes around the bottom edge).
2. Dish and shape the top halves.
3. Weld the top halves together.
4. Grind weld flush on the outside and cleanup weld on the inside if needed.
5. Finish the bottom edge and polish the helmet.
6. Punch the mounting holes in the nasal and rib stop then finish all the edges on them and polish them.
7. Rivet the nasal onto the helmet and then the rib stop.

Use the images below as a guide if you elect to make this SCA-legal.
